686 is probably Pentium2 (as 586 is pentium). "p" means that teh code will use the priviledged instructions so the complier must not complain about it (otherwise it complains like "warning: priviledged instruction at line XXX"). You shouldn't use 'p' uness you're writing an OS or a driver, or whatever similiar.
